In a milling application, all plastics tend to behave differently so attention must be paid first and foremost to heat input, as that greatly impacts surface finish and chip control. Some of Amana Tool carving tools, as you can appreciate have a very small diameter therefore any material chip-loads need to reflect that small size. It can however withstand RPM’s up to 60,000 RPMs. A directed air-blast to keep chips away along with cooling the tool and work piece are always welcome.

Suggested starting spindle speed might be 18,000 RPM, there needs to be some experimenting on the part of the programmer to best find an acceptable finish.
